ANA HEp-2 Screen ELISA

ANA-HEp2 screening ELISA is a solid-phase enzyme immunoassay that is used for the combined qualitative detection of IgG antibodies against HEp2 cells in human serum. This assay can be used for the differential diagnosis of systemic rheumatic diseases, such as systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD), scleroderma, Sjögren’s syndrome, polymyositis and dermatomyositis. Antinuclear antibodies (ANA) against various nuclear and cytoplasmic antigens occur frequently in systemic rheumatism, so they are an important tool for differential diagnosis.
